A major report on how Ireland should tackle greenhouse gases has been passed by the Joint Oireachtas Climate Action Committee.
Sixteen TDs and Senators from Fine Gael, Fianna Fáil, Labour, the Greens, as well as Independent Deputy Thomas Pringle, voted in favour of the report.
However, Sinn Féin and People Before Profit opposed it.
The report secured majority rather than unanimous support due to the inclusion of provision on a carbon tax.
The measure would see carbon tax increasing from €20 to €80 per tonne by the year 2030 - but this can "only be implemented" after impact assessments on those at risk of fuel poverty.
While carbon tax was the most contentious issue, the report is a wide-ranging document covering all aspects of climate action.
It will now be sent to Minister for Climate Action Richard Bruton, to form the basis for the new Government strategy on tackling greenhouse gas emissions.
Mr Bruton said: "I will now consider these recommendations.... Climate disruption can no longer be ignored, we must respond."
Green Party leader Eamon Ryan said: "I am proud of our report which I think is of some significance."
Sinn Féin said it is "...clear and unambiguous on the issue of increases in carbon tax - we are absolutely opposed to them."
People Before Profit said: "Despite many good suggestions and recommendations, the report... has only one actual actionable suggestion that is likely to see the light of day - an increase in carbon taxes."
